You don’t even need grade school science to know that water flows wherever gravity pulls it. But somehow when poured onto Arthur Carabott’s intriguing fountain, it instead sticks to impossibly perfect straight paths and corners on its way down.

NeverWet is a water-repellent spray that can basically keep anything dry. It's cool, if not the most practical thing in the world. But apply it to a sidewalk, let it rain, and magical things start to happen.

When we tried the first iteration of Rustoleum's seemingly magic, liquid-repelling spray, we were actually pretty damn impressed—water beading off toilet paper rolls! Now, though, NeverWet's come out with a version that doesn't leave a gross residue. And while this new NeverWet may indeed be less sticky, it is a hell…

We've had a quite a bit of fun covering anything we could get our hands on with water-repelling magic, but the folks over at Adafruit took it a step further and risked a little electrocution. But the result—submersible circuit boards—is definitely cool enough to be worth the trouble.

Over the past month or so, the internet's been drooling over a promotional video for Rust-Oleum's magical new liquid-repelling treatment. And rightly so! According to the promotional video, no matter the type of liquid, sauce, or lurid emulsion, all offending gunk immediately slides away from treated objects. But…

I can't stop watching this informercial for NeverWet, a superhydrophobic spray that will coat anything—clothes, furniture, even your cellphone—to protect it against any liquid imaginable. I don't know what kind of nanotechnology magic it uses, but Gizmodo says you can now buy it at Home Depot.

Water and electronics are not good bedfellows, but a new silicon-based sprayable coating that makes gadgets completely waterproof has me even more excited for its other applications. Like making clothing impervious to food stains, as demonstrated in this video.
